The Ram 4000 Camshaft - COMP Cams - Thumpr NSR - '17-'18 is a high-performance camshaft designed specifically for the Ram 4000 series, from 2017 to 2018. Known for its exceptional power gains and the distinctive 'Thumpr' idle, this camshaft is the perfect choice for automotive enthusiasts looking to enhance their vehicle's performance without extensive modifications.

The COMP Cams Thumpr NSR camshaft brings cutting-edge technology to the modern Dodge HEMI engines, specifically tailored for the Ram 4000's 5.7L platform. Unlike traditional camshafts that compromise low-RPM torque, the Thumpr series provides a racecar-like lope while maintaining the necessary torque for street-driven vehicles. Notably, this camshaft is designed to be a straightforward upgrade with no need for valve spring replacements. To optimize performance, it is recommended to pair the camshaft with an ECU tune and a DOD deletion, as well as a phaser limiter for VVT-equipped GEN IV HEMI engines, ensuring optimal compatibility and efficiency.
